Title: Mobile drill stand
Inventor: NICKEL MANFRED HERMANN CHRISTI
IPC: B25H1/00
Filed: 1986-12-09
Abstract: Apparatus in order, during free-hand drilling, to carry out said drilling with a low degree of force and high accuracy. For this purpose, in the case of a drill stand (operating plate, drill column, drilling-machine securing means with handlebar), the operating plate is replaced by a bar and the handlebar is replaced by a rotatable handle or lever, by means of which the drilling-machine securing means is moved. Since, during the operating procedure, the apparatus is held by both hands (one hand operates the drilling machine and the other hand produces the movement of the drilling-machine securing means) and, moreover, a stopping point is produced by the bar, located behind the workpiece, the drill is fixed to a sufficient extent and drilling can be carried out with the required accuracy. For better fixing, the abovementioned bar can be replaced by a vice or a clamp.

Title: Device for influencing biological potential differences
Inventor: MERK HANS-DIETER
IPC: A61N1/10
Filed: 1987-05-04
Abstract: A device for influencing biological potential differences for the purpose of stimulating or influencing the metabolism, essentially comprises control electronics with current supply and a power flux generator for generation of voltage surges (in the millivolt range) with a pronounced voltage-time surface in the cells through which the power flux flows in order to increase the ion dynamics by additional ion migration caused in this way. The power flux is controlled in pulses, predominantly in the 10 Hz range, the direction of the voltage surges produced in each case varying. In order to influence the human organism dynamically the pulses are combined into packages which are each followed by a quiescent period of the order of magnitude of one package duration before the next pulse package starts, and so on. The design of the device depends on its intended use.
Patent DE-3720824-A1 (DE)
Title: Device for drilling and drilling-open teeth
IPC: A61N1/34
Filed: 1987-06-24
Abstract: The invention relates to a device, consisting of a dental unit, for drilling and drilling-open teeth, which can be used to achieve an extensive reduction in pain in conjunction with ease of manipulation without additional stress to the patient and without unfavourably influencing the fingertip feeling (lightness of touch) of the dentist during drilling. This is achieved according to the invention when a circuit partially extending through the body of the patient has connected in series the drill (19) with handpiece (18), a voltage source (11), a switch (13), an adjustable resistor (12) and a micro-ammeter (14). It is expedient for there also to be present a pulse shaper (15) which can be used to select the characteristics of the pulses and a pulse limiter (17), as well as a control circuit (16) which keeps the pulse data automatically controlled to the selected values. For the purpose of insulation, the dentist would have to work using protective rubber gloves, but this would unfavourably influence the required fingertip feeling. Consequently, in a further embodiment of the invention the handpiece of the drilling engine is anodised, rinsed (soaked) and coated with a suitable insulating means. After the rinsing, the contents of the surface pores of the handpiece are sucked out in vacuum, and either a treatment with fatty acid and coating with varnish undertaken in vacuum or a coating of photo-resist is applied in vacuum, of which the molecular chain is smaller than the pore diameter, and ...

Filed: 1987-06-30
Abstract: At least two contact pairs, a gear wheel and a leaf spring are provided in a pulse generator, the end of the leaf spring engaging in a latching manner in a tooth gap of the gear wheel, in the quiescent position. After each rotation angle, corresponding to one tooth pitch, after deflection by a tooth, the end of the leaf spring springs into the next tooth gap in a latching manner and, depending on the direction of rotation of the gear wheel, one of the contact pairs can be switched per tooth pitch in each case once. To avoid missing pulses, or additional pulses as a result of contact bouncing, one of the contact pairs (33, 35; 33, 36; 34, 37; 34, 38) is arranged on each side of the leaf spring (12). Movable transverse slides (17, 18) are assigned to the leaf spring (12) such that, when the gear wheel (7) rotates in the one direction of rotation, the first transverse slide (17) can move, and the first contact pair (34, 37 and/or 37, 38) can be operated, and the second transverse slide (18) remains in its quiescent position, and such that, on rotation of the gear wheel (7) in the other direction of rotation, the second transverse slide (18) can move, and the second contact pair (33, 36 and/or 33, 35) can be operated, and the first transverse slide (17) remains in its quiescent position. In addition, such a pulse generator is of compact construction and can be produced economically.

Inventor: ROEHL FRANZ
IPC: B65G53/46
Filed: 1987-07-07
Abstract: The device for transferring granular dry material into a pneumatic feedpipe (32), for example a concrete spraying machine, consists of a material-feeding hopper (4) having a blocking slide valve (6) which can be actuated by a pneumatic working cylinder (8). Arranged one behind the other underneath the blocking valve (6) are two tube sections (16 and 22) which are each subjected to the action of a tube-squeezing device (34 and 38 respectively), between which the tube sections (16 and 22) form a sluice chamber (44) which is additionally provided with a blowing-air connection (62). The blocking valve (6) and the upper tube-squeezing device (34) form a prechamber (42). When the upper tube-squeezing device (34) is closed and the blocking valve (6) is open, the prechamber (42) is filled by free fall from the feeding hopper (4). The sluice chamber (44) can at the same time be discharged into the pneumatic pipe (32) by opening the tube-squeezing device (38). The top (6) and bottom (38) blocking elements then close again and the contents of the prechamber (42) are discharged into the sluice chamber (44) by opening the upper tube-squeezing device (34). The tube-squeezing devices (34 and 38) work against an empty tube. The only blocking elements in contact with the material is the blocking valve (6). Otherwise, the device has no sealing parts which are subject to wear. <IMAGE>

Abstract: Polymer resin or cellulose solutions in plasticisers result in a primer, which has particularly good filling power and 100% solids, for waterborne coating materials, which primer prevents the swelling of the wood by the waterborne coating materials which are subsequently applied, and also does away with the need for drying intervals, penetrates the wood and restores it, ensures a good bond with the polymer resins of the waterborne coating materials, and elasticises them.
Patent DE-3802906-A1 (DE)
Title: Grippable toy for infants
IPC: A63H33/00
Filed: 1988-02-01
Abstract: The handles used for known grippable toys, which are to be gripped laterally, may present safety defects in handling, because the handle has to project sufficiently far beyond a handle plate for the child to be able to grip it securely and at the same time, for the same reason, has a relatively small diameter. In this arrangement, however, the danger exists that when the handle is inserted into the mouth it may make contact in the throat area of the child. In the new grippable toy, this danger is eliminated in that a mushroom-shaped handle is used, which must be gripped at the front. As a result, the grip can be of very low design so that it does not make contact with the throat area, even if its diameter permits insertion into the mouth of the child. The invention is particularly suitable for baby rattles made from wood.

Title: Flow indicator
Inventor: KINAST PETER DIPL ING
IPC: G01F1/28
Filed: 1988-04-21
Abstract: The invention relates to a flow indicator in the drip chamber of medical conduction systems. At flow quantities above 10 millilitres per minute the flow quantity can no longer be determined by means of the usual drip rate, because a continuous stream of the medium forms in the inlet of the drip chamber. By means of an impact plate positioned on a spring and a scale applied to the transparent wall of the drip chamber, the volume flow of the flowing medium can be made visible and indicated to an order of magnitude, in that the stream directed against the impact plate presses the latter downwards in the chamber against the spring force. The flow takes place via apertures in the impact plate which are arranged on the end or around the periphery.

Title: Ink-ribbon transport device in power-driven typewriters or office machines of similar construction
Inventor: PENNING WILFRED
IPC: B41J33/14
Filed: 1988-05-04
Abstract: Modern typewriters and office machines of similar construction have type carrier carriages which can be moved along the recording medium and on which, in addition to the type carrier, an ink-ribbon cassette and an ink-ribbon transport device including its electrically operable drive means are also arranged. The type carrier carriage thus has many components and assemblies to be mounted. The aim of the invention is to simplify the ink-ribbon transport device and its mounting on the carriage and to reduce the production and adjustment costs thereof, the functional reliability being constantly guaranteed. This aim is achieved by the side wall (15) of the carriage (4) having a journal (19), on which a gear (20) with one clutch half of a free-wheeling clutch, which gear can be brought into engagement with the drive pinion (21) of the drive motor, a spur gear (24) of a gear train with the other clutch half, and a carrier (10), on which the drive wheel (37), which can be locked against back-rotation by a pawl (36), is rotatably mounted with the firmly connected other plane gear (35) of the gear train, with a bearing bore (44), are arranged so as to be slipped on one after another and, via catch elements arranged on the carrier (10), can be engaged on the carrier (10) of the side wall (15) in such a manner that the free-wheeling clutch can be held securely and the gear train can be held in engagement without play. As a result, a simple mounting of the ... Original abstract incomplete. <IMAGE>

Title: Method and a device flowed through by a gas, in particular air, for carrying out the method
Inventor: KEHRMANN HELMUT
IPC: G05D7/06
Filed: 1988-05-06
Abstract: In a method and a device flowed through by a gas, in particular air, having a volumetric gas meter which is driven by a servo motor and whose rotational speed is adjusted to correspond to the desired flow, the pressure difference measured by means of two overload-safe pressure difference transmitters of different sensitivities, whose measuring ranges overlap in complementary fashion, being controlled in such a way that the pressure difference tends to zero, a most rapid adjustment of the pressure difference from zero is achieved in the event of sudden flow changes such as occur particularly in dynamic operation. This is achieved in that an electrical output signal, proportional to the pressure difference, from a pressure difference transmitter and an output signal proportional to the time integral of the pressure difference supply the set point for a cascaded positional control of a control element dispensing the flow of the gas, the position of the control element being adjusted so that the pressure difference across the gas meter tends to zero.

Patent DE-3819832-A1 (DE)
Inventor: SPAETH MICHAEL DR
IPC: A62C4/00
Filed: 1988-06-10
Abstract: The invention relates to the inhibition of the propagation of a fire in a building along ventilation ducts. To this end, a lattice of highly heat-conductive material, such as expanded metal, is introduced into the cross-section of the ventilation duct and is able to conduct heat away to the walls of the ventilation duct and hence prevent or delay the breaking-through of the flame. Since such a lattice becomes soiled during the operation of the ventilation plant, it must be easy to exchange and clean. For this reason, it is advisable to introduce the filling in the form of expanded metal spheres laid loose on a strong intermediate level made from transverse struts or perforated sheets, etc.
